I'm not sure whether that could be classified as the recovery phase of exercise, as you were just slowing down a bit, not stopping, right? Also, when studies report on ectopics, they talk about frequency of those ectopics - once in awhile is not supposed to be a big deal, and since this is a one-off occurrence (so far, anyway), it wouldn't seem to be something a doctor would worry much about. In the study I referenced earlier, any # of
PVCs less than 6 per minute during cooldown were not supposed to show an increased risk of anything.
And I know what you mean about not being able to breathe - I'm not sure if it stopped me from breathing, but it stopped me in my tracks as I was walking across a room. It was a sharp little twinge of pain that seemed timed perfectly with the heartbeat. At the time I was a full-on stress monkey, and had been visiting my doctor regularly to figure out some other unusual gastronomical symptoms. While the gastro issues weren't the original cause of the stress, they certainly added to it. Once the stress was mitigated, so were those pains, as well as a few others.
Re: your grandfather - those kinds of stories help to make the rest of us feel better about living to a ripe old age despite having skips and blips.
Are you under a lot of stress lately?
